1.1.2 Performance of the CPU Flashcards
Why does cache size affect the performance of the CPU (2)
Data is transferred faster (1) Makes the CPU more efficient (1)
How can having a higher processor affect the performance of the CPU (2)
Faster/ Higher clock speed (1) More Fetch Execute Cycles (1) More Instructions can be executed per second
Explain why having a quad- core processor will not always run twice as fast as a dual- core processor (3)
Software may be designed to run 1 core and not multiple (1) Dual core may have a faster clock speed than a quad core (1) Quad core may have less RAM (1) Quad core may have less cache (1)
What is Cache Memory (2)
High speed memory inside the processor (1) that stores frequently used insructions (1)
